Airworthiness Directive · Amendment 39-14231 · Saab Model SAAB 2000 Airplanes
Saab Model SAAB 2000 Airplanes
This AD applies to certain Saab Model SAAB 2000 airplanes having serial numbers 004 through 063 inclusive, certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for certain Saab Model SAAB 2000 airplanes. This AD requires an inspection for cracking of the fastener holes in the front and rear spars, a modification of the fastener holes of the front and rear spars and the rear spar web, and related investigative/corrective actions if necessary. This AD is prompted by a report of cracking of certain fastener holes in the lower spar cap of the rear spar and in the lower skin at the front spar. We are issuing this AD to prevent cracking of the front and rear spars, which could result in fuel leakage and consequent reduced structural integrity of the wing structure.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Prior to the accumulation of 20,000 total flight cycles, perform non-destructive tests for cracking of the fastener holes in the lower spar cap of the rear spar and in the lower skin at the left-hand and right-hand sides of the front spar, between WS20 and WS83 inclusive; by accomplishing all the actions specified in Parts A, B, and C of the Accomplishment Instructions of Saab Service Bulletin 2000-57-038, Revision 01, dated June 24, 2004. If any cracking is detected, before further flight, repair the cracking according to a method approved by the Manager, International Branch, ANM-116, Transport Airplane Directorate, FAA; or the Luftfartsverket (LFV) (or its delegated agent).
Prior to the accumulation of 20,000 total flight cycles, modify the fastener holes of the front and rear spars and the rear spar web, including related investigative actions, by accomplishing all the actions specified in Part D of the Accomplishment Instructions of Saab Service Bulletin 2000-57-038, Revision 01, dated June 24, 2004. If 1/4 -inch fasteners are needed for holes No. 7 and No. 8, before further flight, contact the Manager, International Branch, ANM-116, for further actions, or the LFV (or its delegated agent). If any scratches or other damage is detected on the skin surface or the surface of the front spar, before further flight, repair in accordance with a method approved by the Manager, International Branch, ANM-116, or the LFV (or its delegated agent).
Inspections or modifications accomplished before the effective date of this AD in accordance with the Accomplishment Instructions of Saab Service Bulletin 2000-57-038, dated December 18, 2002, are considered acceptable for compliance with the corresponding actions specified in this AD.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
